摘　　要：电动汽车内置式永磁同步电机(IPMSM)主要利用其磁路不对称性的特点来进行弱磁控制,以达到提升电机调速范围的目的,因此分析电机参数对弱磁运行性能的影响具有重大意义。同时为解决IPMSM在弱磁扩速时交、直流电流强耦合的问题,采用一种新的单电流调节器的弱磁控制方式,该方法具有结构简单、动态响应快、参数鲁棒性好等优点。搭建系统Matlab/Simulink仿真模型,并在以TC1782为主控芯片的电动汽车驱动控制系统平台上对该控制策略进行验证。For flux-weakening control of electric vehicles, it mainly uses the electromagnetic circuit asymmetry of interior permanent magnet synchronous （IPMSM） motor to expand the speed.Therefore, it has great significance to analyze the influence of motor parameters on flux-weakening operation performance.This paper adopts a new method of single current regulator to solve the strong coupling problem on flux-weakening expandtion of the speed.The method has the advantages of simple structure, fast dynamic response, good robustness, etc.To verify the feasibility of the control strategy,a Madab/Simulink modeling is established.Finally,TC1782 as the main control chip is used to build the drive system platform of electric vehicle to test the proposed control strategy.
